Living things need energy. Why? To grow, heal, move and more. For plants, animals and
fungi, the energy comes from cellular respiration. That's why cellular respiration is one of
the most important biochemical processes for life on Earth. Wondering what a biochemical
process is? Biochemistry combines chemistry and biology. It is the study of the chemical
reactions that occur in living organisms. Cellular respiration is really a set of chemical
reactions. There are several steps in the process, but eventually, energy from nutrients is
converted into high-energy molecules, and waste is released. This process illustrates one
characteristic of living things: they take in nutrients and release waste.
Based on the passage, which of the following might a biochemist study?
A) the reactions that occur when acid rain hits a brick building
B) the reactions that occur when a person digests a burger
C) the interactions between different animals in the rainforest
D) the different ways animals respond to being surprised
